- Techniques involving non-linear optimisation.
- Non-linear equations.
- Accurate results.
- Computer-intensive iterative search.
- Requirement of a good initial guess.
- Techniques involving computing perspective transformation matrix.
- Linear equations. Without including lens distortion.
- Poor results.
- Extraction of the parameters from the matrix.
- Solution obtained easily.
- Our approach :
- Initial guess solution: Linear method propossed by Toscani.
- Non-linear optimisation by Newton-Raphson including lens distortion.
